FAN ATTACHMENT FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed March 16, 1907. Serial No. 362,608.

To all whom it may concern:

Be it known that I, WIL IAM W. MORRIS, a citizen of the United States,residing at Portland, in the county of Jay and State of Indiana, haveinvented certain new and useful Improvements in Fan Attachments forSewing-Machines, of which the following is a specification.

This invention relates to fan attachments for sewing machines and otheranalogous machines at which operators are supposed to be seated, andwhich provides a simple yet highly efficient means whereby suchoperators may be fanned while thus seated, and with a very slightexpenditure of additional power.

The invention forming the subject of this patent is of simpleconstruction, is easily applied to or detached from the machine, and isnot liable to easily become out of order.

The specific improvements forming the subject of this invention arespecifically described and claimed hereinafter, and illustrated in theaccompanying drawings forming part of this specification and in whichFigure 1 is a general perspective view of the invention applied; Fig. 2is a side elevation partly broken away, and Fig. 3 is a verticalsectional view of the clamping means.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral 10 indicates the table of the machine to which this improvedattachment may be secured. :3 The device comprises a vertically arrangedstandard 11 in the form of a rod which may be of any suitable crosssectional form, preferably cylindrical, whereby a greater amount ofadjustability is secured. This said standard is rigidly secured at itslower end to a U- shaped clamping member 12 which embraces the edge ofthe table and is adapted to be secured thereto by means of the clampingscrew 13. The upper portion of said clamp 12 which engages the uppersurface of the table may be roughened if desired to increase the gripbut preferably it is made plain or smooth in order to prevent marring ofthe polish of said table surface. Mounted upon and adjustably secured tosaid standard 11isasupportingarm14ofpeculiar construction. This arm 14is provided with a vertical eye 14 which corresponds in form to thestandard 11 which passes therethrough with an easy fit. As shown hereinthe standard and said eye are circular in cross section and for thisreason said supporting arm may be adjusted circumferentially about thestandard as well as longitudinally thereof. Said supporting arm isprovided further with a transverse socket 14 which lies substantially atright angles to the aforesaid eye 14 and intersecting the same. "Saidsupporting arm is provided at its lower end with anieye 14. A supportingbolt or trunnion 15, provided with a vertical eye215 which correspondssubstantially in size and form with the eye 14 aforesaid is received insaid socket 14 and the said standard 11 passes through said eye 15. Theother end of the bolt 15 is provided with a screw thread 15 for theaccommodation of a thumb nut 16 mounted upon said bolt and intermediatethe ends thereof is a sleeve 17 which has an easy fit upon the bolt andlies snugly between the shoulder 14* of the supporting arm 14 and theaforesaid nut 16.

It will thus appear that the peculiar arrangement of the bolt 15 in thesocket 14 sleeve 17, and thumb nut 16 constitute a simple yetexceedingly efficient means whereby the supporting arm 14 may be clampedin any position upon the standard 11. When thus adjusted the arm 14 isrigid. The lever 18 is journaled upon the sleeve 17 and being slightlyless in width than the length of the sleeve 17 is adapted to oscillatethereupon at all times. Said levcrlS has at one end an arm 18 having aneye 18, and at the other end an arm 18 having an end eye 18'. Securedupon the arm 18 in any convenient or suitable manner, as by brazing,riveting, or by means of screws, there is a spring clamp 19. The end ofsaid spring clamp opposite the one whereby it is secured to the arm 18lies opposite the arm 18*, and is spaced therefrom a sufficient distanceto receive the handle of a fan 19 and which fan handle is held therebyremovably. If desired the screws 19 may be used in order that the saidspring clamp 19 may be adjusted with respect to the arm 18 toaccommodate handles of different size as will be readily understood. Theinvention, however, is not limited to any specific means for attachingsaid spring clamp to the lever. Any suitable elastic means, shown hereinas a coil spring 20 of proper tensile strength, is secured at one end tothe eye 18 and at the other end to the eye 14, and the normal tendencyof this spring is to draw the said arm 18 and the fan carried therebydownwardly. Any suitable traction means such as a flexible connection 21is attached to the eye 18 aforesaid, the other end of said connectionbeing secured to any operating part of the machine with which thisimproved device is adapted to be used. The function of this connection21 obviously is to draw the arm 18 downwardly against the tension of thespring 20. It will thus be seen that the fan-carrying lever 18 isvibrated alternately by said cord and spring.

From the foregoing detail description of the mechanism the mode ofoperation of this device will be appreciated. The standard 11 is firstapplied to the table in any desired location and the supporting arm 14with the parts carried thereby are adjusted to any desired height orangle at the option of the operator and secured in such position uponthe standard by means of the thumb nut and cooperating parts. Theconnection 21 is then secured to the treadle or any other operating partof the machine in accordance with the previous adjustment of thesupport.

It will be understood that the various parts of this invention may bemade of any suitable materiaiand the specific details of constructionmay be varied within the scope of the invention without departing fromthe spirit thereof or sacrificing any of its advantages.

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent of the United States is:
